FUSE GUTTER AND CAPPER.

SPECIFICATION forming part of Letters Patent No. 276,459, dated April24, 1883.

Application filed December 23, 1882. (Model) To a! whom it may concern:

le it known that I, FRANILP. PIOKING, of Spar-kill independence. in thecounty of Pitkin and State of Colorado, have invented a new and improvedFuse Cutter and Capper,

of which the following is a full, clear, and exact description.

The object of my invention is to provide a. new and improved device forcutting fuses and securing explosive caps on the ends of the same.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in w ich similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of my improved fuse-cutter. Fig. 2 is a.perspective view of the some, showing the manner of tapering the end ofa. fuse. Fig. 3 is a. crosssectional elevation through the jaws, showingthe manner of tapering the end of a fuse.-

Fig. 4 is the end of a fuse with the shell of a cap placed on the same,the cup being shown in section. Fig. 5 is a. similar view, showing themanner of pressing the cap on the fuse. Fig. 6 is a longitudinalelevation of the fuser-utter, showing the manner of forming the Fig. 7is a cross-sectional elevation of the same. Fig. 8 is a longitudt rialelevation of the cap, showing the same se cured on the end or a fuse.

The pliers A have three transverse grooves, 13 O l), in theinnersurfacesofeaehja\v,of which grooves the middle ones, 0, are madetapering. The outer groove, l), of one jaw contains a cutting-disk, 1'which is secured transversely in the groove, and which disk, whenlhejaws are closed, passes into a groove, I, in the groove 1) of theoppoiitejaw, and parallel with the The said disk is used to cntal'nse,which is placed in the groove .l) of the opposite jaw, whereupon the twojaws are pressed together, whereby the end of the fuse is cutol'lsqnarely and evenly, and the fuse will not be damaged. The end ofthe fuse l" cntoll' in this manner is placed between the jaws of thepliers and within the tapering grooves O, and is pressed between thesaid jaws, whereby the end of the fuse will be tapered. An explosivecap, G, is then placed on the end of the fuse, and the fuse and the capare placed between the jaws and in the grooves B, and the inner endofthe cap G is pressed on the end of the fuse. The fuse must be taperedso that it will easily enter the cap G. The fuseand the cap are thenheld between the jaws of the pliers in the grooves B, and then annulargrooves aamust be formed in the inner end of the cap to hold the saidcap on the fuse, and part of the metal of the cap must be forced intothe fuse.

This is accomplished by means of ametal strip, H, provided with a.tapering slot, J, and with a handle, K. The projecting end of the cap Gis passed through the slot J and moved toward the narrow end of the sameuntil the edges of the slot press firmly againstthemetal of the cap.'lhenthe plate orstrip II is turned and gradually forces the metal ofthe cap inward, whereby the annular grooves a will be formed. Lho cap isthus held firmly on the fuse and a. perfectly air and water tight jointis formed, and the explosive mass in the cap cannot be injured by wateror in any other way or manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. A fuse cutting and capping toolprovided with the opposite tapering grooves U 0 in its jaws, whereby theend of the fuse may be made slightly conical, as and for the purposespecilied.

2. The combination of the tool having the opposite grooves 13 B in itsjaws, and the metallic strip Ll, having the taperingslot J, as and forthe purpose specified.
